"Or alternately, if ethnicity isn't what you're using as your basis for calling groups of people and their children "uncivilized", what is?"
Culture.
And this debate is equally fascinating and frustrating.
I simply spoke of generic nomadic uncivilised hunters.
And not at all in a bad way, just to illustrate a point. Because to my knowledge yes, nomadic hunting cultures do have similarities. Education seems to be one of those.
Feel free to provide counter examples.
Furthermore, if you didn't have a specific ethnicity in mind, then when you're going off about "natural education", what you're really saying here is "all groups of people that are part of a group I consider 'uncivilized' are the same".
Or alternately, if ethnicity isn't what you're using as your basis for calling groups of people and their children "uncivilized", what is?
